Question

which of the following is a density - independent limiting factor?
seasonal weather
disease
competition
question 15 1 pts
during exponential growth,
the curve on the graph levels off.
the number of individuals in a population increases rapidly
the rate of increase fluctuates.

Explanation:

• For the first question, density - independent limiting factors affect populations regardless of their density. Seasonal weather events like storms or extreme temperatures impact populations without being influenced by how many individuals are in the population. Disease often spreads more easily in dense populations (density - dependent), and competition is more intense in denser populations.
• For the second question, during exponential growth, the population size increases rapidly over time. The growth rate is constant and the graph of population size versus time shows a J - shaped curve, not a leveling - off curve (which is logistic growth), and the rate of increase does not fluctuate but remains constant in ideal conditions for exponential growth.

Answer:

• Question 14: seasonal weather
• Question 15: the number of individuals in a population increases rapidly
